To all whom t may concern Be it known that I, DANIEL P. KELLOGG, a citizen of the United States, and a resident of the city of Los Angeles, county of .Los Angeles, and State of (Jalifornia, have invented a new and useful Improvement in Car-Roofs, of which the following is a specication.

Y This invention relates to freight car roofs, and has for its object the production of a flexible waterproof roof made of fireproof or substantially fireproof materials. A further object of the invention'is a continuous roof without seams or loose joints to open up and leave crevices throu h it. A further o ject is a roof which can e repaired readlylt any point on the line with stock materia Further objects of the invention appear below in connection with the description of the forms of roof shown in the accompanying drawings. The invention consists 1n the use 0f a flexible support for the roof, and in the character of the roof and its manner of attachment to the car, as hereinafter claimed. The details of the invention appear more fully in the following description of the embodiments thereof shown in the drawings.

The same reference characters are used in the several views of the drawings to designate like parts.

Referring to the drawings,

Figure 1 is a plan view of an end portion of a car having a roof embodying the invention, parts of the roof being removed to disclose the construction of the parts beneath;

Fig. 9. is a vertical cross-section through the ridge portion of the roof, on the line 22 in Fig. 1;

Fig. 3 is a vertical cross-section through the eaves portion of the roof, on the line 3-3 in Fig. 1;

Fig. 4 is an underneath view of a ortion of the roof shown in Fig. 3, showlng the construction near the end of a carline; j

Fig. 5 is a cross-section'of the same on the line 5-5 in Fig. 3;

Fig. 6 is a longitudinal section of the roof at the end of the car, on the line 6-46 in Fig. 1;

ig. 7 is a cross-section at and near the eaves of a roof embodying a modied form of the invention;

Fig. 8 is a plan view of a portion of a roof embodying another embodiment of the invention; and

Fig. 9 is a cross-section of the construction shown in Fig. 8 on the line 9-9 in Fig. 8.

The roof shown in Figs. 1 to 6, inclusive, consists of a layer of tar paper 11 coverin the entire car, and over which is a layerl o wire mesh 12 embedded in a suitable waterproof Aroofing cement. A top coat 13 of suitable waterproof cement is put on over the wire mesh layer. The waterproof roof thereby produced is secured in place by nailing the wire mesh before it is embedded in cement to spaced supports 14 which are loosely arranged on the carlines 15 and end plates 16 of the car. The edges of the Vmesh are soldered or otherwise secured to metal eaves flashing strips 17 which are arranged around the top edges of the car. The outer edges 18 of the eaves lashing strips are bent down and loosely hooked under angle strips 19 which are nailed to the sides and ends of the car just below the top. Sheathing boards 20 are arranged lengthwise of the car between the supports 14, leaving a sli ht gap on each side of each support. he sheathing boards 20 may be nailed or otherwise secured on top of the carlines; and the supports 14 are prevented from rising up by angles or cleats 21 which are nailed to their under sides one on each side of each carline. The cleats 21 are spaced from the carlines, and their ends project under the roof sheathing boards but are not secured thereto. The ends ofthe supports 14 are fastened to end angles or cleats 22 which extend nearly from ridge to eaves on each side of the car.

The running boards 23 are nailed or otherwise fastened to spaced running board saddles 24 which fit astride of the ridge of the roof and rest on the plastic rooting. The ends of the running board saddles are bolted to the middle pair of supports 14. This construction permits the running boards, roof covering and supports to move as a whole relative to the roof sheathing boards, carlines and side and end plates.

In ythe modification shownI4 yin Fig. 7, a layer .of canvas 25 is used instead of tar pa per and wire mesh, and is covered by a layer of plastic cement or one or more coats of Waterproof paint 26. The edges of the canvas are turned under and hooked into the folded inner edge of the eaves dashing strip 27 tomake a tight joint. The outer edge of iashing'strip is turned under and loosely hooked under the outwardly projecting ange of the angle bar 28 which is'secured to the side of the car along the eaves.

In the construction shown in Figs. 8 and 9, a sheet metal roof 29 is used instead of a composite roofing, the sheets being soldered or welded to ether. The roof is held to the supports 14 y metal straps30 which pass under the supports and are soldered or otherwise secured to the roof sheets.

It is apparent from the foregoing description that changes in the details of construction may be made without sacrificing the advantages of the invention, and the invention lis not restricted to the precise details of conroof covering and to permit limited freedem of movement of said roof covering with respect to said car.

2. A car roof having a continuous waterproof covering of plastic material extending from side to side and from end to end of the car, stiieners for said covering comprising separately movable supporting and fastening means extending beneath and secured to its under side, said supporting and fastening means on either side of the ridge being connected together and having limited freedom of movement with respect to said car.

3. A car roof having a continuous waterproof covering extending from side to side and from end to end of the car, a supporting frame for the middle portions of said coveri said supporting frame having limited free om of movement with respect to said car, and eaves dashing strips loosely engaging the car at the eaves for movement relatively thereto, said roof covering being fastened to said eaves strips at its edges and to said supporting frame between its edges whereby it is securely held in place throughout the length and width of the car.

4. A car roof comprising al plurality of spaced supports extending lengthwise of the car, a continuous roof secured upon said supports, means for connecting said supports and for movably securing said supports to the car, and means for loosely securing the edges of said roof at the sides and ends of the car.

5. A car roof comprising a plurality of spaced supports extending lengthwise of the car, a continuous roof secured u on said supports, running board supports olted to said supports, means for movably securing said supports to the car and means for loosely securing the edges of said roof at the sides and ends of the car.

6. A car roof` comprising a pluralityl of spaced supports extending lengthwise of the car, a continuous roof secured upon said supports, supporting sheathing arranged between and spaced from said sup orts, and means for movably securing said) supports to the car. l

7. A car roof comprising a luralit of spaced supports extending lengt wise o the car, a. continuous flexible roof rigidly secured upon said supports, supporting sheathing arranged between and spaced from said supports, and means for movably securing sai supports to the car.

9. A car roof comprising a, plurality of spaced supports extending lengthwise of the car, the supports on each 'side of the ridge being secured together by cross-pieces pivoted thereto, a continuous roof secured upon said supports, means for movably securing said supports to the car, and stops for limiting the endwise' movement of said su ports.

10. A car roof comprising a plurality of spaced supports extending lengthwise of the car, a continuous roof secured upon said supports, supporting sheathin arranged between and spaced from sai supports, and means for movably securing said supports to the car, said means comprising cross cleats fastened to the under side of said supports and projecting under the adjacent sheathing.

11. A roof supporting frame comprising carlines, purlins extendinglengthwise of the car over the carlines, said purlins being movI momble transversely of the ce1-lines, and

able lengthwise of the carlines, and roof roof sheathing supported on sid earlines besheathing supported on said carlines between said purlins and spaced therefrom. 10
